I'm going to preface my questions with a (hopefully) brief story:
One of my coworkers is a born again Christian. She had been to church as a child but had largely abandoned it during her early 20s to mid 30s. Her daughter convinced her to "find" Jesus again, so she rejoined a "Mega Church" in her late 30s. She is now in her late 50s. Through various circumstances, this coworker came to have primary custody of her (now 13 year old) granddaughter when the girl was 2 years old. Coworker has always raised her granddaughter in the church and has involved her in several of the church groups and programs over the years.
Recently, the granddaughter has begun going through some difficulties. She's feeling confined, she's feeling rejected by her bio-parents, and she has fears that she will exhibit the same negative characteristics that they have (characteristics my coworker reminds her of rather frequently). Coworker decided to put her granddaughter into therapy, provided through the church, focused solely on granddaughter's "insubordination" and "religious apathy". The underlying and primary issues have (IMO) largely been ignored.
So getting to the topic: Recently, granddaughter has become increasingly frustrated with her environment and circumstances, telling my coworker that she's tired of being forced to talk to the counselor about God. When coworker asked why her granddaughter didn't want to talk about God, granddaughter said, "Because "God", or "Jesus" or whomever..they were just men who were written about by men. And I'm sick of being told I'm disappointing some man who's been dead for thousands of years just because I'm upset with things."
So coworker's response was to ground granddaughter for "saying awful things about God", and increase her "therapy" sessions with the church counselor.
And now the questions: If you are religious, how would you handle your teenage child questioning the beliefs of your religion or challenging the veracity of religious history? Would you allow them to work through their questioning and disbelief and come to their own conclusions, or would you work vigorously and sternly to reinforce their beliefs without regard for their questions or statements of disbelief? Would you find their religious apathy/anger/questioning to be a more serious issue than other psychological issues that might be present?
